UMBRELLA AND PARASOL To all whom it may concern: I v 7 Be it known that I, JAMES Rosie, a citizen of the United States, residing at Lancaster, in the county of Lancaster and State of Pennsylvania, have invented certain new and-useful Improvements in Umbrella and Parasol Frames, of which the following is a specification.

This invention relates to frames for umbrellas and parasols, and it relates particularly to ribs having joints therein which permit the abrupt bending of all the ribs of the article, to give an abrupt bend to the outer edge of the cover'when raised, and thereby impart to it a novel attractive appearance. In ribs of the character referred to as heretofore made the bending of the ribs when the umbrella or parasol is raised, and the return of the ribs to a straight position when closed, has usually been accomplished by pivotally connecting links to the stretchers and to the ends of the ribs, which serve struction is needlessly complicated and'is I made inoperative by slight bending of the parts, by rusting of the joints or by any other slight injury. Another defect in the form of ribs referred to is that the partsof the ribs being straight throughout, a sharp projection is formed at the point of hinging when the ribs are distorted, and this projection is liable to tear or impose undue wear on the cover.

The object of the present invention is to provide ribs to form parts of an umbrella or parasol frame having jointed sections near their ends or in any other desirable position, and having applied thereto a spring which when the umbrella or parasol is closed will return the ribs to a straight position after being distorted by raising.

A further object of the invention is to provide an umbrella or parasol rib having a joint therein, and a spring for straightening the rib when moved to a'closed position, which spring shall be located on the outer face of the rib, next to the cover, when the latter is attached and shall form a curved face at the joint when the rib is bent, thus avoiding injury to the cover and presenting a pleasing appearance when an umbrella or parasol containing it is raised.

With these objects in view the invention consists essentially of an umbrella or para- Specification of Letters Patent. Patented Oct]. 12,1915. i Application filed. January 11, 1911, i Serial No. 602,003.

sol rib having the novel generic and specific features of construction substantially as hereinafter describedand claimed.

The invention is illustrated in theaccompanying drawing'in which;

Figurel is a Side view of an umbrella, in

a raised position, provided-with my novel ribs, a portion of the cover being broken away to show the form and disposition, of the parts; F 1g. 2 is a side view of a portion of a rib containing the novel features, and,

Fig. 3 is a view of the joint and operating spring, the view" being taken from the inner cured to the stick 3, and which are connected by stretchers & to a runner 50f any suitable construction. The ribs are each composed of twoor more sections, they being in the form herein illustrated, made in two parts. The parts of the rib are joined by any suitable .form of hinge connection. In the present form one section is slotted at its end and receives the I end of the other section, the parts being joined by a pin 6 which permits independent movement of the parts.

' It is intended to use the ribs in connec- I tion with a cover 7 having a contracted portion adjacent to the hinge, in order that when the umbrella or parasol is raised the action of the cover will be to bend at their points of hinging in order to give an abrupt bend to the cover. In the form of ribs herein shown the joints are located near the outer be secured to the respective parts 'ofthe ribs in any suitable way, for instance as shown particularly in Figs. 2 and 3 of the drawing. In this form a flat spring is formed with orfhas attached to each end thereof means for encircling the respective parts of the rib. 'One end of the spring is preferably rigidly attached to one part of the rib and the other end is so connected to the other part as to allow a limited sliding movement on the rib as the latter is moved on its hinge. In the form herein shown the spring is bent at one end to closely confine one part of the rib, while the other end isbent to wholly or partially inclose the other part of the rib but to allow slight movement of the part of the rib located therein.

The spring preferably though not neces-' when an umbrella or parasol having the new form or ribs and cover properly contracted, is raised, the springs 8 will be bent uniformly throughout giving the desired curved shape to the downwardly bent edge of the umbrella, and that this bending of thesprings 8 will put them under tension suflicient to insure the straightening of the ribs by them when in lowering the umbrella or parasol the ribs are freed from pressure of the cover. 7

Having thus described my invention, what I claim as new, and desire to secure by Let ters Patent, is

1. An umbrella or parasol rib composed of parts connected by a joint, and a flat spring arranged on the outer faces of the parts and permanently located over the joint, each end of the spring being attached to a part of the rib.

2. An umbrella or parasol rib composed of parts connected by a joint, and a flat spring arranged on the outer faces of the parts extending over the joint and tending to maintain the parts in alinement, the

spring being permanently located over the joint and each end of the spring being attached to a part of the rib.

3. An umbrella or parasol rib having a joint therein, a flat spring having one end rigidly attached to the outer face of one part of the rib and having the other end attached to the other part and capable of sliding thereon, the spring extending over the joint connecting the parts.

4. An umbrella or parasol rib made in sections joined at their ends, and a spring extending over the point of juncture, one end of the spring being rigidly connected to one section and the other end thereof being slidably connected to the other section.

5. An umbrella or parasol rib made in sections joined at their ends, and a spring extending over the point of juncture, one end of the spring being bent to closely inclose one section and the other end being bent to loosely inclose the other section.

6. An umbrella or parasol comprising ribs having joints therein, a cover having a contracted portion adjacent to the joints, whereby when the umbrella or parasol is raised the ribs are distorted by pressure of the 'cover, and flat springs attached to the outer faces of the ribs, at the joints whereby the ribs are automatically straightened when relieved of pressure by the cover.

7. An umbrella or parasol comprising ribs having joints therein, a cover having con tracted portion adjacent to the joints, whereby when theumbrella or parasol is raised the ribs are distorted by pressure of the cover, and a flat spring attached permanently to one part of each rib on the outer face thereof, and slidably connected to the other part thereof.

In testimony whereof I afiix my signature in presence of two witnesses.
